[PATCH 1/2] drivers: net: cpsw: fix dt probe for one port ethernet

[Felipe Balbi <balbi@ti.com>]

From: Mugunthan V N <mugunthanvnm@ti.com>

When only one port of the two port is pinned out, then dt probe is failing
because second port phy is not found. fixing this by checking the number of
slaves and breaking the loop.

both patches were taken from TI's 3.12 tree [1]
and have been tested on am335x, am437x and
dra7xx.

Mugunthan, I took the patches because I got bug reports
on v3.13-rc which these patches fix. Let me know if you
prefer to send another version of them for whatever
reason.

cheers
